WINDOW-CLEANING DEVICE.

Application filed February 26, 1926. Serial No. 90,866

This invention relates to improvements in window cleaning devices, and has particular reference to a hand operated device for cleaning the inside and outside of window panes.

The principal object of this invention is to provide means whereby a window may be cleaned upon both sides while the user remains on one side thereof.

Another object is to provide means wherebe adjusted to accommodate for various sizes of Windows.

Another object is to provide means whereby the portion of glass customarily inaccessible when the window is partly open, may be elliciently cleaned.

A further object is to provide a device of this character which is compact and one which may be folded into a minimum amount of space.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a fragmentary vertical crosssection of a window showing my device in use thereon,

Figure 2 is a perspective view of my device,

Figure 3 is a fra entary detail view showing the scrubber li ding employed independently of the handle,

Figure 4 is a detail view showing the manner of employing a scrubber at a point where the windows overlap,

Figure 5 discloses the manner of applying the scraper and squeegee to the window pane,

Figure 6 is a front elevation of the scrubber,

Figure 7 is a side elevation of the element,

Figure 8 is a back plan view of the scraping element, and

Figure 9 illustrates my device in folded position.

It is common to wash windows on the outside by leaning out of the window. or sitting in the window-sill, so that the major portion of the washers body is on the outside of the window. Either of these practices is dangerous and have resulted in serious injuries.

I have, therefore, devised a whereby the outer surface of scraping the window simple tool 8 may be washed with equal facility as it is possible to wash the inner surface of the window. By inner and outer surface of a window, I mean the side of the window pane toward the room or away from the room.

In the accompanying drawings wherein for the purpose of illustration isshown a preferred embodiment of my invention, the numeral 5 designates the window casing within which sashes 6 and 7 are slidably sup-.

ported. The sash '6 has a window pane 8 and the sash 7 a window pane 9. The inner surface of these window panes is indicated at A and the outer surface at B.

In Figure 1, the sash 6 has been raised above the window sill 11, in order to permit my tool to be passed beneath the sash. This tool comprises a bar 12 to which is clamped a lever 13 as by a clamp 14 which is contracted by a wing nut 16, and pivoted as at 17 to the lever 13. This lever 13, is pro vided with a handle 18 by which the device is manipulated.

At 19, I have shown a tubular sleeve slidable upon the lever 13 and having pivoted thereto a link 15 to the free end of which is pivoted a ring-shaped member 15 or collar, which encircles the bar 12. The collar 15 is spaced from the clamp 17 by a spacer link 15".

The bar 12 carries at its upper extremity an implement 22 pivoted as at 23 to the looped portion of a supporting wire 24. The ends of this supporting wire aresecured to a tubular sleeve 26 which is adapted to be engaged by the rod 12. The implement shown at 22 in Figure 1 may be termed a scrubber and is adapted to lie parallel with the window pane 8, as is diagrammatically illustrated at C in Figure 5. r

In order to dry the window after the same has been scrubbed, I provide in lieu of the scrubber a window scraper and squeegee. This device is illustrated in Figures 7 and 8 and consists of a rectangular plate 28 having a bracket 29 secured thereto. This bracket includes hinged portions and has one portion free as shown at 38, which enables the wire 24 to be received in a groove 32 formed in the portions, and said wire is held against withdrawal from the groove by a pivoted latch member 27, as shown in Figures 3, 7 and 8 of the drawings. A rubber squeegee 31 is also secured thereto, as well as a scraper The manner of employing this combined per and assesses is llus ted in F u 5. The ositwn employed or scraping is illustrated it A and the position employed for squeegeeing is illustrated at B.'" When the device is us'edwithin the house and upon the inner side of the window pane the wire 24 is removed from'the rod 12 together with its tubular member 2Q a fter which the device maybe emplbyed as shoivn N ith Figure 3 Q Fi u 41 In using either the scraper or the squeegee thesameiis turned end for end so that the 7 part contacting thew-indoxvis uppermost.

I When using the device upon the outer surface of the window the handle '18 is gms sd with one h 16 and, the tubular mem er 1%) is grasp withfthe'other'hand. proper manipulation of the twohands, the Scrubber or squeegee may be caused to W 1 9W he t re g tside Sur th w ll l m thqnt mces i y '0f the ope tor leaning out ofthe iv'indqw, therehyfendangerin g himself.

It is to be understood that the form of my ev e ie h wi h shown and described is to be taken as a preterred example of the same, and that such changes 1n the shape,

size and arrangement of parts may be resorted to as do not depart from the spirit of the invention or the-scope of the subjoined cleim.
